The RS 3’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The M2 doesn’t offer pre-crash pretensioners.
For enhanced safety, the front seat shoulder belts of the Audi RS 3 are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW M2 doesn’t offer height-adjustable seat belts.
The RS 3 has a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The M2 doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
The RS 3 has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The M2 doesn’t offer all-wheel drive.
The RS 3’s optional blind spot warning system uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. The M2 doesn’t offer a system to reveal objects in the driver’s blind spots.
To help make backing out of a parking space safer, the RS 3’s optional rear cross-path warning system uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The M2 doesn’t offer a cross-path warning system.
Both the RS 3 and the M2 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems and rearview cameras.
